orbeon - スタックオーバーフローが発生するまで Orbeon Forms が XForms で無限の再検証を行う原因は何ですか?

Question

Orbeon Forms CE バージョン orbeon-4.0.0.M11.201210030654-CE を使用しています。

複数のインスタンスを持つ XForm (XHTML) があり、インスタンスの 1 つで required="true()" を使用してバインドし、xxforms-invalid と xxforms-valid を使用してケースを切り替えました。以下は、私の xform からのコードサンプルです。

<xforms:instance id="teaching-load-instance" src="oxf:/apps/uis-common/model/uis-teaching-load-xforms-instance.xml"/>

<xforms:bind nodeset="instance('teaching-load-instance')/teaching_load">
    <xforms:bind nodeset="module_id" required="true()"/>
</xforms:bind>

<xforms:action ev:event="xxforms-invalid" ev:observer="teaching-load-instance">
    <xforms:toggle case="invalid-form-case"/>
</xforms:action>

<xforms:action ev:event="xxforms-valid" ev:observer="teaching-load-instance">
    <xforms:toggle case="valid-form-case"/>
</xforms:action>

この xform ページにアクセスすると、stackoverflow エラーがスローされます。

XForms では無限ループを作成できますが、この場合、XForms エンジンのバグに遭遇したようです。xf:toggleケースが変更されていない場合、は効果がありません。これについては問題を記入しました。追跡できます。

この問題は、Orbeon Forms 4.0 M13 以降で修正されています。if以前のバージョンでは、にを追加することで回避できますxf:toggle。スイッチIDがmy-switch次のとおりであると仮定します。

<xforms:toggle if="xxforms:case('my-switch') != 'invalid-form-case'"
               case="invalid-form-case"/>

さらに、同等のものifを他のに追加し<xforms:toggle case="valid-form-case"/>ます。

orbeon - スタックオーバーフローが発生するまで Orbeon Forms が XForms で無限の再検証を行う原因は何ですか?
